section along line ZIJ- 20 Referring now more particularly to the draw` ings in which like reference characters indicate like elements throughout the frame for the window, according to the invention, may be made of wood, metal or other suitable material adapted to fit masonry, brick or other openings as required. The lintel l is preferably provided with a longitudinal groove 2 for receiving the top rail of the top sash when it is is in closed position.

Similarly the sill 3 is rabbeted at Il to receive the lower rail of the lower sash when the latter is in closed position.

The window frame is provided all around its outer edge with an abutment 5 projecting inwardly into the window opening and against which is set two side pla-tes 6 which are perma 3 nently secured to the jambs 1 of the window frame by means of screws 8 or the like.

The side plates 6, having L-shaped section as shown in Figures 1 and 8, extend the whole height of the window opening and are preferably made in extruded metal sections which may be cut to the desired length. They are provided with a longitudinal dovetailed groove 9 for interlocking with the corresponding dovetail projections I of the upper glass pane guide member II as shown in Figure '1, said latter member II being further secured to the side plate 6 by means of the screws B.

The upper guide members II extend downwardly from the top or head of the window frame to about middle height and their lower edge I2 is bevelled as shown in Figure or 6.

The upper guide members Il are flat members provided with inward projections I3 and I4 spaced from each other and from the longitudinal edge of the guide member II so as to define channels for slidably receiving the glass panes I5 and I6. The side edge portions of the glass pane I5 of the lower inner sash is slidably inserted between projections I3 and I4 while the glass pane IB of the upper outer sash slides between the projection I3 and the inwardly projecting leg I1 of the L-shaped permanently affixed side plates 5. The projections I3, I4 and leg I1 have preferably dovetailed grooves for receiving the weather strips I8 to ensure airtight joints between the glass panes and the metal frame sections.

The upper guide members II are further provided with a beaded portion I5 forming a circular groove the purpose of which will be described hereafter.

The lower glass pane guide members 23 have exactly the same cross-section as the upper glass pane guide members Il except that the dovetail. projection I0 is eliminated thereby permitting free lateral displacement of said lower guide members 23 relatively to the fixed side plates 6. They are bevelled at their upper end 2| to register with the lower bevelled end I2 of the fixed upper guide members Ii and they are pivoted at their lower end for inward swinging movement on the hinge plate 22 which is fixed to the sill 3 by means of screws 23.

The hinge proper comprises an I -shaped rod 24 having one leg freely extending within the sleeve 25 of the hinge plate 22 and the other leg freely inserted into the beaded portion I9 of the lower guide members 2U. Thus the latter may be easily and rapidly removed from their hinge connections to the sill 3 as shown in Figure 3.

The lower end portion 25 of the guide members 20 is milled as shown in Figure 5 to allow movement over the hinge plate 22.

The guide members 20 may be swung inwardly and adjustably secured at any desired angle. Arms 26 are pivotally secured at their lower end by a pin 21 to a bracket 28 secured to the jamb 1 of the window frame by means of screws 23. The upper end of said arms is pivotally secured by a pin 3!) to an extension 3| depending from a guide rod 32 slidably inserted into the beaded portion I9 of the lower guide member 20. A locking device, consisting in a disc 33 eccentrically mounted on the pin and having a knurled periphery 34 to press against the outer face of the beaded portion I9 when rotated by means of the ringer grip 35, serves to lock the guide rod 32 relatively to the guide member 20.

The lower guide members 20 are locked in closed position to the upper guide members II by means of a locking bolt 36 freely slidable in the beaded portion I9 of the guide members II and 20 and provided with a manipulating arm 31 which may be inserted into a slot 36 of the beaded portion I9 of the upper guide member II when the bolt 36 is in locking position or which may be inserted in a bracket or keeper 39 affixed to the top sash member 40 of the lower sash as shown in Figure 5. The arm 31 is placed in the latter position when the bolt 36 is in unlocking position its free upper end being below the upper edge 2| of the lower guide members 2B as shown in Figure 6.

The lower inner sash comprises the glass pane I5 and the top and bottom horizontally extending sash members 40 and 4I respectively, while the upper outer sash comprises the glass pane I6 and the horizontally extending top and bottom sash members 42 and 43 respectively. These sash members are cut at a suitable length to extend between the inner rabbeted shoulders I4 and I1 of the projections I4 and legs I1 of the guide members II and 20 and of the side plates 3 respectively.

These sash members have preferably a U- shaped cross-section, the inner face of their legs being serrated for gripping the edge portions of the glass panes I5 and I6 which are covered with suitable glazing strips so as to allow endwise entry of said glass panes between said legs but to prevent their removal.

The sash members may be removed from the glass panes by a sideways movement which may be effected only when the window is dismounted as shown in Figure 3 and after the glass pane guide members 20 have been removed.

The top sash member 42 of the outer sash is preferably provided with a circular groove 44 for the insertion of a suitable weather strip not shown. The lower sash member 5.3 is provided with a similar circular groove 45 into which may be inserted suitable blocking means, not shown, to secure the top sash in adjusted vertical position. The groove 45 also receives a hook 46, the purpose of which will be described hereafter.

The inner side face of the sash member 43 is provided with a dovetailed groove for the insertion of a weather strip 41, which is adapted to contact the top sash member 4I) of the inner sash when the window is in closed position.

The sash member 40 is provided with an outer projection 48 at its end, adapted to overlap the sash member 43 to further insulate the window, according to the inventionI when the sashes are in closed position.

A latching member 49 serves to lock the two sashes in closed position. It is inserted in the sash member 40 as shown in Figures 5 and 6, and is pivoted in a horizontal plane on a screw 50 to have its outer end 5I project within a registering groove 52 made in the sash member 43.

The lower sash member 4I of the inner sash is provided with a bottom circular groove 53 for the insertion of suitable means, not shown, to adjustably secure the bottom sash for different degrees of opening. The lower sash member 4I is further provided at its lower edge with an outwardly projecting curved extension 54, and also with a manipulating' extension 55 projecting inwardly from the top edge thereof.

The sash member 4I is further provided with an inclined face 56 adapted to ensure a leakproof contact with the inclined face of the rabbet 4 of the sill 3 when the window is in closed position.

As shown in Figure 9, the hooks 46 are pivotally secured in groove of the sash member 43. The edges of the grooves 45 are punched in as shown at 51, thereby providing stop means to limit the sideways displacement of the hooks 16. These hooks 126 serve to displace the outer sash by operating the inner sash as shown in Figures 10 to 12.

To lift both sashes, the hooks 46 are swung inwardly so as to rest upon the extension 54 of the member 4I as shown in Figure 10. Thus by manipulating the extension of the latter the top sash member 44 may be driven into the recess 2 of the lintel I. To lower the two sashes, the hooks 46 are swung outwardly as shown in Figure 11 so that they may engage the underportion of the extension 54 as shown in Figure 12. The two sashes may then be displaced downwardly by means of the manipulating extension 55 of the inner sash.

In order to prevent falling apart of the outer glass pane I6 when swung inwardly in its lower position between the glass pane guides 20, the latter are provided with suitable retaining means for the glass pane such as the L-shaped leaf spring 58 shown in Figure 8 secured to the outer edge of said guide members 26. It is obvious that under these conditions the weather strips I8 on the leg I1 will extend only at the top half portion of the window opening.

In Figure 13 the window is shown with the sashes in closed position; in Figure 14, the top sash is partially opened; in Figure 15, the bottom sash is partially opened; in Figure 16, the bottom sash is swung inwardly together with the glass panes guide members 26 while the top sash is in its uppermost position, and in Figure 17, both sashes are swung inwardly.

Figures 18 to 20 show a double double-hung window built according to the present invention. the elements previously described are simply duplicated except that the outer or double window will have preferably a smaller width so as to swung inwardly.

Instead of having a double double-hung window as shown in Figures 18 to 20, double glass panes with an air space left therebetween may be substituted to the single glass panes l5 and I6.

From the foregoing description, it is seen that the window, according to the invention, may be easily installed for any size of opening, all the standardized construction and having simply to be cut to the right dimensions. This double-hung window may be swung inwardly and locked at any suitable angle for proper ventilation. Furthermore, the sashes and the side glass pane guides 20 may be completely removed from their hinges for cleaning, reglazing, etc.

While a preferred embodiment according to the invention has been illustrated and described it and in two sections, the upper section the top portion of said side plate, the

secured to lower secfil tion in closed position.
